Kit Overview

The Texas Instruments' Medium Voltage Digital Motor Control Kit for Stellaris® Microcontrollers (DK-LM3S-DRV8312DK-LM3S-DRV8312) is a development platform for spinning 3-phase brushless DC (BLDC) motors. The low-cost Stellaris LM3S818LM3S818 microcontroller (MCU) on the MDL-LM3S818CNCDMDL-LM3S818CNCD controlCARD module comes pre-programmed with the necessary firmware in flash memory to run the Texas Instruments' (TI) InstaSPIN™ BLDC motor control solution out-of-the-box once plugged into the DRV8312DRV8312 baseboard. The system will automatically detect and spin a customer’s 3-phase brushless DC motor.

The operation of this system is controllable and viewable across a USB interface using an included Crosshairs-enabled GUI environment that consists of a PC application interface and Crosshairs’ embedded kernel running on the LM3S818LM3S818 MCU. The LM3S818LM3S818 MCU provides all of the necessary computational requirements to run TI’s InstaSPIN BLDC technology and other customer-developed applications as well.

The LM3S818LM3S818 microcontroller is targeted for industrial applications, including test and measurement equipment, factory automation, HVAC and building control, motion control, medical instrumentation, fire and security, and power/energy. In addition, the LM3S818LM3S818 microcontroller offers the advantages of ARM's widely available development tools, System-on-Chip (SoC) infrastructure IP applications, and a large user community. Additionally, the microcontroller uses ARM's Thumb®-compatible Thumb-2 instruction set to reduce memory requirements and, thereby, cost. Finally, the LM3S818LM3S818 microcontroller is code-compatible to all members of the extensive Stellaris family; providing flexibility to fit our customers' precise needs.

Key applications: Industrial, Test and measurement equipment, Factory automation, HVAC and building control, Motion control, Medical instrumentation, Fire and security, etc.
